Agent Skills: resonance-strategy-grill

The pre-build interrogation gate. Stress-tests a plan, design, or goal contract through one-question-at-a-time questioning and targeted risk passes before any code is written, so hidden assumptions surface while they are still cheap to fix. Use before starting a feature, refactor, migration, new project, or when the user says grill me, pressure-test this, poke holes, or challenge this idea. Reaches explicit shared understanding and gates implementation until the user confirms.
